There is a country that fits into that time gap that is hot and doesn’t have a race yet... Australia!
Every international series comes to Australia, except for FE. Strange it hasn’t happened yet.
(Which also raises the question of why no race in Japan. Seems an obvious place to have on the calendar)
I do not remember any street races in Japan. Is there perhaps some restriction on them? Or are Japanese cities simply too busy to close off streets for racing?
